SPECIFICATION forming part of Iletters Patent No. 275,474, dated April10, 1883.

Application filed August 24, 1882. (No model.)

To all whom it may concern:

Be it known that we, JOHN H. EWING and EDWARD L. BILL, of Wheeling, inthe county of Ohio and State of West Virginia, have invented certain newand useful Improvements in Lamps and Lanterns; and we do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

Our invention relates to an improvement in lamps and lanterns, and moreparticularly to globes and chimneys therefor, the object being toprovide improved meansfor attaching lenses to the articles mentioned.

With this object in view our invention consistsin certain details ofconstruction and combination of parts, as will be hereinafter explained,and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in front elevation of alantern-globe constructed in accordance with our invention. Fig. 2 isaview thereof in vertical section, and Figs. 3, 4, 5, 6, 7, and 8 showsectional views ofmodi fled forms which our invention may assume.

A represents a globe, which may be appropriately modified-in size andshape to fit different styles of lanterns and lamps. It is constructedin any suitable and approved manner and provided during the process ofconstruction with one or more flat-faced annular extensions, B,virtually consisting in projected portions of the globe. The outer endsof the said extensions are encircled by flanges O, which are dividedinto two or more segmental sections by openings D, the same beingdesigned to receive fingers E, which extend inwardly from the annularsettings F of the lenses G, and which are arranged to coincide inposition with the position ofthe said openings D. In securing the lensesto the globes, the fingers are first introduced into the openings. Whenthis is effected the lenses are revolved sufficiently to engage thefingers with the rear faces of the flange-sections. In detaching thelenses from the globes the said fingers are brought into positions ofcoincidence with the openings, thus disengaging them from theflange-sections and permitting the removal of the lenses.

Crystal glass is preferably employed in the fabrication of the globes,which may be, if desired, ground or flashed with colored glass, leavingthe faces H of the extensions 13 untouched. As to thev lensesthemselves, they may be formed from crystal or colored glass, and ifcrystal glass is employed in their fabrication,and it is desired tocolor the transmitted light, their inner or outer faces may be flashed,as shown at I in Fig. 3 of the drawings, with colored glass. Thecoloration of the transmitted light may also be effected by flashing thefaces H with colored glass, as shown at J, or by the interposition ofpanes K, ofcolored glass, between the said facesH and the lenses.

It is apparent that a lamp or lantern provided with a globe constructedin accordance with any of the above-recited methods will constitute asignaling apparatus easy to operate, and having a very wide range ofeffect.

The extensions B are closed by their flat faces, and this is thepreferred construction, inasmuch as the lenses may be manipulatedwithout in any way disturbing the body of air inclosed by the globe;but, it found desirable, the extensions may be left open.

. In the modification shown in Fig. 3 of the drawings the lens isprovided with resilient a flange, (3, like the flange shown in Fig. 1 ofthe drawings.

The lens shown in Fig. 5 of the drawings is mounted in an annularmetallic setting having a screw-threaded flange, O, projectin ginwardl yfrom it, said flange being adapted to be screwed over a fiangelessscrew-thread extension, P.

In the modification shown in Fig. 6 of the drawings the setting of thelens is provided with a plain inwardly-projecting annulus, Q, designedto be secured to the flan geless extension R by cement.

In Fig. 7 of the drawings a lens having an inwardly-extending flange, S,formed integral with it is shown, said lens being cemented to tions tooffer a firm hold for the cement.

The lens shown in Fig.8 of the drawings has an interiorly screw-threadedflange, U,formed flangeless extension T, provided with corrugaintegralwith it. This lens is illustrated as in engagement with a flan gelessextension,V,provided with small projections W, which engage with thescrew-threads of the flange U, and take the place of continuousscrew-threads shown in the flan geless extension P.

Our invention is not limited to globes and chimneys; but cylinders andall other glass articles for inclosing and protecting flames may beadapted to have lenses attached to them in the manner shown.

In view, then, of the modifications above suggested, and others of likecharacter which the invention embraces, we would have it understood thatwe do not limitourselves to the exact construction shown and described,but that we hold ourselves at liberty to make such changes andalterations as fairly fall within the spirit and scope ofour invention.

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is

l. The combination, with a globe or chimney having one or moreflat-faced extensions, of lenses and devices associated with the lensesand arranged to engage with the peripheries of the said extensions.

2. The combination, with a globe or chimney having one or moreflat-faced extensions encircled by flanges, of lenses andfin gersattached to or made integral with the lenses and arranged to be engagedwith the flanges of the extensions, substantially as set forth.

3. The combination, with a globe or chimney having one or moreflat-faced extensions encircled by flanges having openings in them, oflenses and fingers associated with the lenses and arranged to coincidewith the openings in the flanges, substantially as set forth.

4. The combination, with a globe or chimney having one or moreflat-faced extensions, the same being encircled by flanges, of lenses,annular metallic settings in which the lenses are mounted, and fingersattached to or made integral with said settings, and arranged to engageWith the flanges of the extensions, substantially as set forth.

In testimony whereof we have signed this specification in the presenceof two subscribing witnesses.
